Booster doses of COVID-19 vaccine

The Australian Technical Advisory Group on Immunisation (ATAGI) have recommended a booster dose of COVID-19 vaccine for people who are aged 18 years and over (link)

You are eligible for a COVID-19 booster dose if:

  • you are 18 years and older, and
  • have had your second dose of COVID-19 vaccination at least 6 months ago.


Booster doses are not mandatory, however they are recommended to maintain immunity against COVID-19.

A booster dose increases your protection against:

  • infection with the virus that causes COVID-19
  • severe disease
  • dying from COVID-19.


A booster dose will continue to protect you, your loved ones and your community against COVID-19.

Booster doses will be free for everyone.

Vaccine types for booster doses

The Pfizer vaccine is approved by the Therapeutic Goods Administration (TGA) and recommended by ATAGI as a COVID-19 booster dose. 

You can have the Pfizer vaccine as a booster dose regardless of which vaccine you had for your first 2 doses.

You can also receive the Vaxzevria (AstraZeneca) vaccine if you:

  • can’t have the Pfizer vaccine for medical reasons
  • had 2 doses of the AstraZeneca vaccine previously.

After Your Vaccination

After receiving any vaccine, you may experience minor side effects. Most side effects are mild and last no more than a few days.

Common reactions to COVID-19 vaccinations include:

  • a sore arm
  • headache
  • low level fever
  • muscle pain
  • chills
  • tiredness, or
  • joint pain.


You can use the COVID-19 vaccine side effects symptom checker if you have concerns about any symptoms after your vaccine. The checker is also available through the National Coronavirus Helpline, 1800 020 080, 24 hours a day.
